Description of key information

No data on the biodegradation in simulation tests is available.

Key value for chemical safety assessment

Additional information

No data on biodegradation in sediments and surface water are available. However, further biotic degradation testing shall be proposed if the chemical safety assessment according to Annex I indicates the need to investigate further degradation of the substance and its degradation products. The test substance was found to be poorly biodegradable in an OECD 301B study and poorly eliminated from water in a modified sturm test according to 84/449/EEC, C.5. It is assumed that the test substance is not biodegradable in simulation tests either. Therefore, simulation studies on surface water and sediments are not provided.
